 Syntax:  Round (RealVar) ;

 Type:    Integer

 Form:    Function

 Purpose: Round RealVar to the nearest integer.

 Notes:   If RealVar >= 0 then Round (RealVar) = Trunc (RealVar + 0.5).
          If RealVar <  0 then Round (RealVar) = Trunc (RealVar - 0.5).

 Usage:
       CONST
          Real1  : Real =  2.5    ;  { IntVar =  3 after Round }
          Real2  : Real =  0.5    ;  { IntVar =  1 after Round }
          Real3  : Real = -3.4    ;  { IntVar = -3 after Round }
          Real4  : Real = -0.6    ;  { IntVar = -1 after Round }
